  • What I want for Matz-mas Andrew Grimm @andrewjgrimm
  • $VERBOSE = true
    • Not my talks – I want it in Ruby 2.0!
  • $VERBOSE = true
    • Warns you about misspelled instance variables
    • Warns you that (false; true) is legal but pointless
    • Warns you that you aren't using a variable
  • Who do I want using it?
    • People who are going to ask “Why doesn't this code work?” questions on Stack Overflow
    • People who write libraries
  • Hash.default_proc
    • If I could set a global default proc for Hash#fetch, I wouldn't need:
      • hash.fetch{ raise “The key #{key.inspect} doesn't bloody exist”}
  • Better support for FP
    • I want to keep up with functional programming
    • I'd rather do it with Ruby than without Ruby
  • Better support for FP
    • Ban side effects from part of your program?
    • Haskell process:
    • 1. No side effects
    • 2. Profound embarassment
    • 3. ???
    • 4. Awesomeness
  • Better books about Ruby
    • Ruby has the same book published in a hundred editions
      • Metaprogramming
      • DSLs
      • method_missing
      • monkeypatching
    • They're showing off what Ruby can do, rather than help you accomplish your mundane task
  • Should I have to read “Smalltalk Best Practice Patterns” in order to know how to program in Ruby ?
  • What needs to be written about?
    • How to write maintainable Ruby code
      • And rescue poorly written Ruby code
    • Object oriented Ruby
    • Functional programming Ruby
    • Ruby that fails fast
    • How to optimize Ruby
  • My ideal second Ruby book
      1. A n00b is doing it wrong on Stack Overflow 2. I say “Ah – you're doing antipattern X. Please see page 42 of 'U R doing it wrong in Ruby'” 3. The n00b is enlightened
    • Why? Because I'm still a bloody n00b!
  • Some books that are pretty decent
    • Metaprogramming Ruby
    • Everyday scripting with Ruby
    • Eloquent Ruby (for n00bs, anyway)
    • The Pickaxe
  • Ruby community
    • How much are we learning?
    • Why can't we get more non-beginner-level questions on Stack Overflow? Do you honestly think you know everything?
  • Ruby community
    • Starting to realize that persistence might be separate from business logic
      • Gee, ya think!
  • Ruby community
    • I want you guys to learn an awesome language
    • It's called Ruby
  • Less discriminatory humour
    • I'm not opposing sexism in the hope that it'll lead to a more diverse community
    • Not being a boofhead is its own reward
  • Why I'm sick of sexism
    • Intrinsically bad
    • Unprofessional
    • Makes me ashamed to by a (Ruby) programmer
  • Last and not least
    • I want it to scale!
